TECHNICAL FIELD

The present invention relates to a novel organic metal complex derivative and an organic light emitting device using the same.

This application claims priority benefits from Korean Patent Application No. 10-2007-0088451, filed on Aug. 31, 2007, the entire contents of which are fully incorporated herein by reference.

BACKGROUND ART

In general, the term “organic light emitting phenomenon” refers to a phenomenon in which electric energy is converted to light energy by means of an organic material. The organic light emitting device using the organic light emitting phenomenon has a structure usually comprising an anode, a cathode and an organic material layer interposed therebetween. Herein, the organic material layer may be mostly formed in a multilayer structure comprising layers of different materials, for example, a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, an electron injecting layer and the like, in order to improve efficiency and stability of the organic light emitting device. In the organic light emitting device having such a structure, when a voltage is applied between two electrodes, holes from the anode and electrons from a cathode are injected into the organic material layer, the holes and the electrons injected are combined together to form excitons. Further, when the excitons drop to a ground state, lights are emitted. Such the organic light emitting device is known to have characteristics such as self-luminescence, high brightness, high efficiency, low drive voltage, wide viewing angle, high contrast, and high-speed response.

The materials used for the organic material layer of the organic light emitting device can be classified into a light emitting material and a charge transporting material, for example, a hole injecting material, a hole transporting material, an electron transporting material, and an electron injecting material, according to their functions. The light emitting material can be classified into a high molecular weight type and a low molecular weight type, according to their molecular weight, and divided into a fluorescent material from singlet excited states and a phosphorescent material from triplet excited states according to their light emitting mechanism. Further, the light emitting material can be classified into a blue, green, or red light emitting material and a yellow or orange light emitting material required for giving more natural color, according to a light emitting color.

On the other hand, an efficiency of a device is lowered owing to maximum luminescence wavelength moved to a longer wavelength due to the interaction between the molecules, the deterioration of color purity and the reduction in light emitting efficiency when only one material is used for the light emitting material, and therefore a host/dopant system can be used as the light emitting material for the purpose of enhancing the color purity and the light emitting efficiency through energy transfer. It is based on the principle that if a small amount of a dopant having a smaller energy band gap than a host which forms a light emitting layer, excitons which are generated in the light emitting layer are transported to the dopant, thus emitting a light having a high efficiency. Here, since the wavelength of the host is moved according to the wavelength of the dopant, a light having a desired wavelength can be obtained according the kind of the dopant.

In order to allow the organic light emitting device to fully exhibit the above-mentioned excellent characteristics, a material constituting the organic material layer in the device, for example, a hole injecting material, a hole transporting material, a light emitting material, an electron transporting material, and an electron injecting material should be essentially composed of a stable and efficient material. However, the development of a stable and efficient organic material layer material for the organic light emitting device has not yet been fully realized. Accordingly, the development of new materials is continuously desired. The development of such a material is equally required to the above-mentioned other organic electronic devices.

The organic metal complex derivative according to the present invention can be applied to the organic light emitting device by a typical preparation method of organic light emitting device.

In one embodiment of the present invention, the organic light emitting device has a structure comprising a first electrode, a second electrode, and organic material layers disposed therebetween, and can be prepared by using typical method and materials, except for using the organic metal complex derivative according to the present invention as the organic material layer of organic light emitting device. The structure of the organic light emitting device according to the present invention is illustrated in FIGS. 2 to 6.

For example, the organic light emitting device according to the present invention can be prepared by depositing a metal, a metal oxide having conductivity, or an alloy thereof on a substrate using a PVD (physical vapor deposition) process such—as sputtering and e-beam evaporation to form an anode; forming an organic material layer comprising a hole injecting layer, a hole transporting layer, a light emitting layer, and an electron transporting layer on the anode; and depositing a material, which can be used as a cathode, thereon.

The organic matter layer may be a multi-layer structure including a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, etc., but is not limited thereto. As a result, the organic matter layer may be a single layer structure. Also, the organic matter layer can be prepared in a very small number of layers by a solvent process, not by a deposition, for example, spin coating, deep coating, doctor blade, screen printing, inkjet printing, thermal transfer using various polymer materials.

Generally, the following materials can be used for a hole injecting material, a hole transporting material, a light emitting material, and electron transporting material.

The hole injecting material is a material facilitating hole injection from an anode at low voltage. The HOMO (highest occupied molecular orbital) level of the hole injecting material is preferably located between the work function of the anode materials and the HOMO level of its neighboring organic material layer. Specific examples of the hole injecting material include organic materials of metal porphyrin, oligothiophene, and arylamine series, organic materials of hexanitrile hexaazatriphenylene and quinacridone series, organic materials of perylene series, and conductive polymers of anthraquinone, polyaniline, and polythiophene series, but are not limited thereto.

The hole transporting material is preferably a material having high hole mobility, which can transfer holes from the anode or the hole injecting layer toward the light emitting layer. Specific examples thereof include organic materials of arylamine series, conductive polymers, and block copolymers having both conjugated portions and non-conjugated portions, but are not limited thereto.

The light emitting material are a material capable of emitting visible light by accepting and recombining holes from the hole transporting layer and electrons from the electron transporting layer, preferably a material having high quantum efficiency for fluorescence and phosphorescence. Specific examples thereof include 8-hydroxyquinoline aluminum complex (Alq₃); compounds of carbazole series; dimerized styryl compounds; BAlq; 10-hydroxybenzoquinoline-metal compounds; compounds of benzoxazole, benzthiazole, and benzimidazole series; polymers of poly(p-phenylenevinylene) (PPV) series; spiro compounds; and compounds of polyfluorene and rubrene series, but are not limited thereto.

The electron transporting material is suitably a material having high electron mobility, which can transfer electrons from the cathode to the light emitting layer. Specific examples thereof include 8-hydroxyquinoline aluminum complex (Alq₃); complexes including Alq₃; organic radical compounds; and hydroxyflavone-metal complexes, but are not limited thereto.

The organic light emitting device according to the invention may be of a front-side, backside or double-sided light emission according to the materials used.

The compound according to the invention can function in an organic electronic device including an organic solar cell, an organic photoconductor, and an organic transistor, according to a principle similar to that applied to the organic light emitting device.
